trying to get the test name right, failed, gave up and used a sequence
number instead. When I realized it wasn't because of the number of
underscores in the name that I really started to think. I didn't have
braces around the variable names ...
Thus: test_1 is now called apm_1x1_512_qcow, which gives you all you
need to run mkimg by hand.
